Hello! I am glad to see that another fan is working on Brigandine. The TIMs you posted look nice. You did a good job of matching the font styles in the menu TIM.
If you want to translate the game menus into Russian, you will probably have to edit pointers. I have some TXT documents that show some pointer locations, but they are not complete yet.
You asked about narrow letters like "I": the font in STAY.BIN is 8x12 per letter, but I injected a process that checks which letter is being drawn, and moves the boxes closer together if needed. Since the box is invisible except for the letter, it doesn't matter if the 8x12 boxes overlap.
The standard Russian text system uses 2 bytes per letter, correct? The first thing you need to decide is will you be using a 2 bytes per letter encoding, or a system that uses 1 byte per letter.
Another note, the main menu TIM uses 48 different pallets (CLUTs) and the one you posted is using pallete #1. If you need to revise anything in your TIM, it might be easier to use other palletes. Like pallete #5 that shows the ingame color for the menu labels.
